blood pressure

We've all heard the advice to go easy on the salt shaker. Or, perhaps, more importantly, to cut back on eating packaged, processed foods that often contain a lot of salt.

And why? There's a lot of evidence linking excessive sodium intake to high blood pressure, which increases the risk of heart disease.

The dietary guidelines recommend that adults consume no more than 2,300 milligrams of sodium per day.

Young people in their teens and early 20s probably aren't thinking about heart disease. But maybe it's time they did.

People who have slightly higher blood pressure when they're 18 to 25 are more likely to have high blood pressure and hardening of the arteries in their 40s, a study says. About one quarter of the people in this study were in that group.
